A rubber strip25 is fixed at the end; therefore, the ring magnet 23 and the magnetbase 24 are fixed to fix the box body 14, and at the same time, themagnet base 24 drives the magnet block 28 to slide upward.

In the following, the applicant will refer to the accompanying drawingsand the specific composition of a multifunctional hub of the presentapplication described above to introduce its use in detail:

When the ring magnet 23 is not attracted to the magnet base 24, the ringend gear 13 meshes with the locking teeth 12 and the fixing block 11cannot rotate. Before the hub is firmly fixed, the winder does notperform the winding function, so as to avoid the Everywhere

When the ring magnet 23 is attracted to the magnet base 24, the ringmagnet 23 repels the magnet block 28, the magnet block 28 slides upward,the magnet block 28 drives the first ejector rod 29 to push the thirddisc 51, and the slider 50 slides on the ratchet The claw 46 is engagedwith the internal ratchet teeth 45, and at this time, the winding can benormally wound into the winding groove without loosening;

At the same time, the magnet block 28 drives the second ejector pin 36to slide upward through the hydraulic pipe 30. The second ejector pin 36pushes the ring slider 15 upward, and the ring slider 15 slides upwardto disengage the locking tooth 12 from the ring end face gear 13. Thering slider 15 can rotate, and at the same time, the height differencebetween the top surface of the gear 17 and the ring gear 16 forms a teacup placement opening with an upward opening, which can stably place thetea cup;

Extend the wire into the wire slot 33, align the wire with the card slot41, and fasten it into the card slot 41 from bottom to top. Then rotatethe handle 10, the handle 10 drives the gear 17 to rotate, and the gear17 drives the first A disk 42 rotates, and the first disk 42 drives thewinding groove 43 to wind the wire to collect the wire. It does not needto be manually fixed during winding, and the operation is simple;

When you need to loosen the wire, press the gear 17, the gear 17 drivesthe spline shaft 19 to slide down, the spline shaft 19 drives the firstdisk 42 to slide down, and the first disk 42 slides down to make theinternal ratchet teeth 45 and the pawl 46 is disconnected. At this time,the first disc 42 can be rotated in the reverse direction, that is, thewire is pulled to make the winding groove 43 reverse to loose the wire.When the cable is loosened and pressed, the hub plays the role of wiregathering again.

To sum up, the multifunctional hub of the present invention is simpleand clear in operation, sensitive in response, time-saving andlabor-saving; meanwhile, the device of the present invention is rich infunctions, firmly fixed and practical.
